An indium(II)-indium(II) compound with intramolecular donor-acceptor bonds
摘要:
The diindium compound {2,6-(Me2NCH2)(2)C6H3} (Cl)In - In(Cl) {(2,6-Me2NCH2)(2)C6H3} (2) has been prepared via the reaction of [(2,6-Me2NCH2)(2)C6H4]InCl2 with Li-2[(C4H4BN(Pr-i)(2)]. By means of X-ray crystallography, it was established that four N --> In donor-acceptor bonds are made to the unsuspended In-In moiety: monoclinic, space group C-2/c, with a = 21.913 (6), b = 8.364 (1), c = 17.877 (3) Angstrom, alpha = 90, beta = 117.21 (2), gamma = 90 degrees, V = 2914 (1) Angstrom(3) and Z = 4.
